冠词和数词

1 不定冠词的用法

冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article)。

不定冠词a (an)与数词one 同源,是"一个"的意思。a用于辅音音素前,一般读作[e],而an则用于元音音素前,一般读做[en]。

1) 表示"一个",意为one;指某人或某物,意为a certain。

A Mr. Ling is waiting for you.

A knife is a tool for cutting with.

Mr. Smith is an engineer.

3) 词组或成语。

He bought a house.I've been to the house.

他买了幢房子。我去过那幢房子。

4)单数名词连用表示一类事物,如:the dollar 美元;

the fox 狐狸;或与形容词或分词连用,表示一类人:the rich 富人; the living 生者。

5)用在序数词和形容词最高级,及形容词only,very,same等前面:

Where do you live?I live on the second floor.你住在哪?我住在二层。

That's the very thing I've been looking for.那正是我要找的东西。

6)与复数名词连用,指整个群体:

They are the teachers of this school.指全体教师)

They are teachers of this school.(指部分教师)

7)表示所有,相当于物主代词,用在表示身体部位的名词前:She caught me by the arm..她抓住了我的手臂。

8)用在某些由普通名词构成的国家名称、机关团体、阶级、等专有名词前:

the People's Republic of China中华人民共和国

the United States美国

Brave a man though he is,he trembles at the sight of snakes. 他尽管勇敢,可见到蛇还是发抖。

当名词被比较级形容词修饰时,不定冠词通常置于比较级形容词之后。
